Catchment Productivity Controls Local Species Richness of Hyporheic Invertebrate Communities in Tropical New Caledonia Streams

open access: yesEcology and Evolution, Volume 15, Issue 12, December 2025.
How does the local species richness (LSR) of stream invertebrate communities relate to the terrestrial productivity of the stream catchment? Using generalized linear models and variance partitioning, we quantified the independent and joint effects of local and catchment predictors on LSR of hyporheic invertebrate communities in New Caledonia streams ...

Next‐Generation Therapies for Gastrointestinal Repair: Converging Traditional Medicine and Tissue Engineering

open access: yesJGH Open, Volume 9, Issue 12, December 2025.
ABSTRACT The gastrointestinal (GI) tract plays a vital role in regulating metabolic pathways, nutrient absorption, and cellular homeostasis. Abnormalities in the GI tract often arise from unhealthy lifestyles, genetic mutations, and prolonged medication use, leading to disorders such as ulcers, cirrhosis, and malignancies.

The exceptional stem cell system of Macrostomum lignano : screening for gene expression and studying cell proliferation by hydroxyurea treatment and irradiation [PDF]

open access: yes, 2007
BackgroundFlatworms are characterized by an outstanding stem cell system. These stem cells (neoblasts) can give rise to all cell types including germ cells and power the exceptional regenerative capacity of many flatworm species.

New records of nine monogenean parasites infesting non‐native freshwater fish species in New Zealand

open access: yesNew Zealand Journal of Marine and Freshwater Research, Volume 59, Issue 5, Page 1052-1068, December 2025.
ABSTRACT Twenty‐one non‐native freshwater fish species have established populations in New Zealand, yet only two have been reported with monogenean infestations; grass carp, Ctenopharyngodon idella (Valenciennes in Cuvier and Valenciennes, 1844) and western mosquitofish, Gambusia affinis (Baird and Girard, 1853), each with two identified monogenean ...

Wetland biodiversity in Aotearoa New Zealand: an eDNA perspective on exotic and non‐exotic species

open access: yesNew Zealand Journal of Zoology, Volume 52, Issue 4, Page 410-427, December 2025.
ABSTRACT Invasive species threaten biodiversity in Aotearoa New Zealand. In wetlands − significant sites that provide an array of ecosystem and cultural services but represent <10% of their original extent − invasive species can affect hydrological function, nutrient regimes and overall ecological functionality.

Far From Roads, Challenges Arise: Unravelling Knowledge Gaps in the Occurrence of Cave‐Restricted Species on the African Continent

open access: yesAfrican Journal of Ecology, Volume 63, Issue 8, December 2025.
ABSTRACT Understanding patterns of biodiversity distribution is fundamental for ecology, biogeography, and conservation. However, persistent challenges arise from the inaccessibility of many regions and habitats. Subterranean environments, in particular, host highly distinctive and specialised faunal assemblages, yet their investigation is hindered by ...
